Active Directory​/Identity Engineer; Senior

Computer World Services, Corp. (CWS) seeks a Senior Active Directory / Identity Engineer to own and sustain the Microsoft Active Directory Domain Services (AD DS) environment supporting the USMEPCOM ENLIST program. This senior engineering position manages AD objects, organizational units, Group Policy Objects (GPOs), trusts, replication, schema governance, delegated permissions, domain services, and recovery capabilities.

The engineer also evaluates and tests approved Identity, Credential, and Access Management (ICAM) capabilities, including potential Okta integrations. These modernization activities complement, not replace, the need for direct, hands‑on AD DS engineering expertise. The engineer works closely with cybersecurity, Service Desk, systems, cloud, network, application, COOP, and Government identity stakeholders.

• Install, configure, maintain, troubleshoot, and recover AD DS, and create, modify, disable, and delete authorized users, computers, groups, service accounts, and other directory objects.
• Design and maintain the OU structure, and manage OU permissions and delegated administration using least-privilege principles, correcting excessive or conflicting access.
• Develop, test, deploy, and troubleshoot GPOs, including links, inheritance, precedence, security filtering, WMI filters, backups, and recovery; assess changes for security and customer impact before production.
• Configure, validate, and troubleshoot domain and forest trusts, reviewing direction, transitivity, authentication scope, and name-suffix routing.
• Maintain AD sites, subnets, site links, and replication topology; troubleshoot replication failures, latency, and lingering objects; and maintain domain‑controller health, SYSVOL, DFSR, time sync, AD‑integrated DNS, and FSMO roles.
• Plan and execute domain‑controller installation, upgrade, demotion, and retirement and transitions to supported AD versions; govern and coordinate controlled schema extensions.
• Process escalated account, group, and permission changes; troubleshoot authentication, authorization, policy, trust, and replication issues; and improve identity‑related Service Desk routing and knowledge content.
• Provide advanced support during identity and authentication incidents, elevate widespread failures through incident‑responsе procedures, and support root‑cause analysis and corrective actions.
• Develop, maintain, and test AD backup, authoritative and non‑authoritative restoration, deleted‑object recovery, and forest‑recovery procedures, and support COOP and disaster‑recovery exercises.
• Support integration testing between AD and Okta or other approved identity platforms, validating synchronization, authentication flows, attribute and group mappings, provisioning, and SAML, OIDC, OAuth, SCIM, or LDAP protocols, and documenting test results.
• Automate approved directory administration, health validation, and reporting; review audit information; apply DISA STIGs and security baselines; and support RMF controls, POA&M activities, and remediation.
• Maintain SOPs, recovery plans, configuration baselines, and directory diagrams, and provide directory‑service health, risk, and modernization information for program reporting.

• Bachelor’s degree in Information Technology, Information Systems, or a related field, or equivalent professional experience where permitted by the labor category.
• Minimum of eight (8) years of relevant experience in Active Directory engineering, identity engineering, Windows infrastructure, systems engineering, or a related…
